-This is an internal design that needs to be fitted over an existing chip as well as a few lines to be soldered to various points on the CPC motherboard. It's a DIY kit, essentially. No direct orders, so you have to register on the CPC Wiki forum and contact the designer on there. //Note: As of 2019, the developer is no longer making these available.//

+Don't have one (yet), but this enables you to use a PS2 keyboard on a VIC20, C64 or C128.
+//"Depending on configuration, C=Key offers VIC-20, C64, C64C, SX64, C128, C128D, and C128DCR owners the ability to either use their CBM keyboard with a PS/2 supported PC, or utilize a PS/2 keyboard on their Commodore machine.  In either usage, multiple keyboard mappings are supported, to handle keyboard differences and application preferences.  No drivers or programming are required for operation.
+C=Key can be purchased in the following configurations:
+PCB Only: Bare circuit board
+PCB + uC: PCB and programmed Atmel ATMEGA162, used for connecting CBM KB to PC (includes uC Crystal and trimming capacitors)
+PCB + uC + Crosspoint Switch: Allows either configuration
+Preconfigured kits for specific CBM models.
+Full Kit: Adds resistors, diodes, and jumper blocks for correct operation and connectors for any configuration
+Additional options include:
+dual joystick connectors can be added, to allow CBM joystick operation on the PC.
+Any kit can be ordered pre-assembled (please allow additional handling time)"//

 In short, it's very delicate, but only 8x 100Ohm resistors are needed (obviously the traces need to be cut for each one also). The //nicer// solution would be to connect each resistor to a multi-way switch so that the original, unaltered data path can be restored, if for example you decide to disconnect the external keyboard.... though I would guess it should still work when the external interface is removed.
-A detailed diagram of which pins are needed to be altered is to follow below.

+Note: this is another design that will not work on the +2A, +2B or +3 due to the way Amstrad redesigned the main board. This is again for 16K, 48K, 48K+, 128K and +2 models only. **I think I'm going to have to downgrade from the +3 to a +2 in order to get PS2 keyboard support....**
